xcode global nsmutablearray that keeps values

Did a search but cant seem to find exactly what I'm looking for Basically I load values into a nsmutablearray in one method and then I want to access these values in another method to print them to a table I declared the array in the app.h

NSMutableArray *clients;

Then in the app.m

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
      [connection release];
      NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
      [responseData release];
      NSArray *results = [responseString JSONValue];
      clients = [[NSMutableArray alloc]init];

      // Loop through each entry and add clients to array
      for (NSDictionary *entry in results)
      {
           if (![clients containsObject:[entry objectForKey:@"client"]]) 
           {   
                [clients addObject:[entry objectForKey:@"client"]]; 
           }
      }  
}

Now Im try to acces the clients array in another method I have seen some suggestions to use extern in the app.h? Some sort of global variable?

Any help would be appreciated

Thanks

Take the clients array in app delegate class.declare the property,synthesizes in the app delegate class.Then in the below method write like this.

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
      [connection release];

YourApplicationDelegate *delegate = [UIApplication sharedApplication]delegate]; 

  NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
  [responseData release];
  NSArray *results = [responseString JSONValue];

      clients = [[NSMutableArray alloc]init];

      // Loop through each entry and add clients to array
      for (NSDictionary *entry in results)
      {
           if (![clients containsObject:[entry objectForKey:@"client"]]) 
           {   
                [delegate.clients addObject:[entry objectForKey:@"client"]]; 
           }
      }

}

after that suppose you if you want to use the clients array in another class do like this.

YourApplicationDelegate *delegate = [UIApplication sharedApplication]delegate]; 
NSLog(@"client array is %@",delegate.clients);
